Looking for a good quality and cheap ink I'm after some research stumbled upon this third-party next Pelikan and Agfa. Other vendors are quite expensive, but the quality of these no-name manufacturers are by their own experience pure poison for the print heads of the printer. At the latest after a few months back and the printheads are due a new printer again.
If several test results (Stiftung Warentest, c't, Computer Bild) could these ink dots even before the original ink. My Brother Printers (MFC490CW) has accepted these cartridges without hesitation. The results when scanning, printing and copying were perfect. A long-term test is, however, shed light on whether this ink may damage the print head.
In good hope, I give this product 5 stars for the time being.
Addendum 01.30.2015: The ink is very ergiebigig and not dried out. I have another set of purchases since I'm happy with the results.
Addendum 05.28.2015: Amazon raised the price sometimes just by 8.90 euros to 18 euros. What these extreme price increase is I can not understand. There are 3 points deduction because the value for money is no longer true even when compared to the cheap alternative inks.
Addendum 07.06.2015: The price has dropped to 11.25 as well have suffered the orders. Therefore, a better Preisleistungsverhätnis.
